I used to cross paths with this "street person" walking to work. He was usually drunk & pretty obnoxious to a lot of people but I thought he was pretty funny & he was usually cool with me. Once I had a bunch of treats I was bringing for a co-worker's birthday so I gave him a couple. His reaction surprised me. He was so humble & grateful as if noone ever gave him anything... and I realised noone probably did...
